Definitions

  • This invention generally relates to wireless communications telephone devices and, more particularly, to a system and a method for acquiring a channel when activating a wireless telephone device.
  • the wireless device When a wireless communications telephone device is first activated, the wireless device must obtain initialization information and a list of channels to which the wireless device can connect.
  • the initialization information enables the wireless device to find a suitable radio carrier channel and obtain carrier system information.
  • the initialization information is typically included in a Number Assignment Module (NAM) pre-loaded into the wireless device memory.
  • NAM Number Assignment Module
  • the appropriate NAM also can be loaded by the wireless device user into the wireless device using a wireless device user interface. If more than one NAM is pre-loaded in wireless device memory, it is known to have the wireless device user manually select a NAM appropriate for the current wireless device location. However, the wireless device does not include a means for automatically selecting the appropriate NAM.
  • NAMs generally cover relatively large geographical areas, such as a metropolitan region.
  • a Priority Roaming List (PRL) in the NAM typically includes a listing of channel groups. Each channel group is associated with a channel coverage area within the area covered by the NAM and includes the channels for the respective channel coverage area.
  • PRL Priority Roaming List
  • Each channel group is associated with a channel coverage area within the area covered by the NAM and includes the channels for the respective channel coverage area.
  • a wireless telephone user has a contract for services from a particular carrier or provider.
  • Each network carrier has preferences regarding the channels a wireless device acquires in a given channel coverage area. Therefore, the channels in a given channel group are listed according to the carrier's preference.
  • the PRL also includes system information such as base station Network Identification (NID).
  • NID base station Network Identification
  • the wireless device begins the process of acquiring a channel by scanning the channels listed in the PRL.
  • the wireless device begins with the first channel group in the PRL and scans additional groups in the order in which the groups are listed in the PRL.
  • the wireless device scans the channels to acquire a pilot signal with sufficient signal strength.
  • the wireless device acquires the associated synch signal containing system information for the pilot signal channel, such as the NID and the System Identification (SID).
  • SID System Identification
  • the , wireless device compares the synch signal system information with system information listed for the channel in the PRL.
  • the pilot signal is from a base station within the coverage area for the current wireless device location and the wireless device acquires the pilot signal channel. Otherwise, the pilot signal is from a base station outside the coverage area and the wireless device begins scanning again, starting with the next channel listed in the PRL.
  • the wireless device contains a Most Recently Used Table (MRU) listing the channels to which the wireless device has most recently been connected. Upon activation, the wireless device can begin scanning channels listed in the MRU. If the wireless device has not moved too far from the location in which it was last deactivated, a suitable channel may be found in the MRU. Otherwise, the MRU is no longer useful (that is, the channels in the MRU are for coverage areas other than the coverage area in which the wireless device is currently located) and the wireless device must scan channels in the PRL as noted above. Once a wireless device acquires a channel as described above, there are known handoff procedures that enable the wireless device to acquire different channels as the wireless device moves among various cells within a selected NAM coverage area.
  • MRU Most Recently Used Table
  • the wireless device moves into an adjoining NAM coverage area, the known handoff procedures cannot be used since the selected NAM does not contain initialization information or a PRL for the adjoining NAM. In this case, the wireless device goes into deep sleep. That is, the wireless device continues to scan for a pilot signal associated with the selected NAM, but increases the time period between scans to minimize battery usage. It is known to manually load a new NAM when leaving the coverage area for a selected NAM. However, as noted above, the wireless device cannot automatically select an appropriate NAM.
  • a PRL can contain a large number of channels. Therefore, acquiring a channel by scanning channels, beginning at the top of the PRL, can take a significant amount of time, particularly if the desired channel group is near the end of the channel group listings in the PRL.
  • the wireless device is unable to carry out communications functions, such as receiving pages, while scanning channels from the PRL. Therefore, during PRL channel scans, wireless device users are deprived of the use of their devices and carriers are deprived of revenue- generating activity.
  • the present invention addresses acquisition of an operating channel in a wireless communications telephone device.
  • the invention recognizes that acquiring a channel by scanning channels in a Preferred Roaming List (PRL) can take a significant amount of time.
  • PRL Preferred Roaming List
  • the invention also recognizes that the wireless device is unable to carry out communications functions, such as receiving pages, while scanning channels from the PRL.
  • the invention addresses these problems by using geographical location information for the wireless device to select a Number Assignment Module (NAM) corresponding to the current wireless device location.
  • NAM Number Assignment Module
  • the invention also uses the geographical location information to identify channels in the PRL for the selected NAM.
  • a method for expediting acquisition of an operating channel in a wireless communications telephone device.
  • the method activates a wireless communications telephone device and identifies the wireless device geographical location.
  • the method correlates a NAM with geographical location information and selects the NAM.
  • the method also correlates a predetermined group of channels in a Priority Roaming List (PRL) in the selected NAM with geographical location information and selects the channel group.

  • Fig. 1 is a schematic block diagram depicting a system 100 for expediting acquisition of an operating channel in a wireless communications telephone device in accordance with the present invention.
  • the system 100 is applicable to a wireless communications telephone device 102.
  • the wireless device when a wireless device is first activated, the wireless device must access initialization information from a Number Assignment Module (NAM) appropriate for the current location of the wireless device and acquire a channel listed in the appropriate NAM.
  • NAM Number Assignment Module
  • the system 100 enables the wireless device 102 to determine and access this NAM and expedites the acquisition of a channel listed in this NAM.
  • the system 100 includes a locator sub-system 104 and a NAM sub-system 106.
  • the locator subsystem 104 identifies the current geographical location of the wireless device 102 and supplies, at intervals, the location in a location signal from an output on line 110.
  • the locator sub-system 104 can supply location signals at periodic intervals, the frequency of which can be adjusted to meet individual application requirements.
  • the location signal contains a point in a coordinate system defining the wireless device geographical location.
  • the NAM sub-system 106 includes at least one NAM. Each NAM in the NAM sub-system 106 is correlated with geographical location information defining the coverage area for the respective NAM. That is, for a typical two-dimensional orthogonal plane coordinate system, each NAM would be referenced to the coordinate points within the coverage area for the NAM. The number of such coordinate points depends on the size of the coverage area and the scale of the coordinate system. It is understood that the system 100 is not limited to any particular coordinate system.
  • the NAM sub-system 106 has a first input to accept the location signal on line 110. The NAM sub-system 106 determines which of the NAMs in storage corresponds to the coordinate system point in the location signal and selects that NAM.
  • the NAM sub-system 106 includes an output to supply initialization information from the selected NAM on line 112.
  • Each NAM in the NAM sub-system 106 includes a Priority Roaming List
  • the device begins the process of scanning channel groups listed in the PRL for the selected NAM.
  • the channel groups in the NAMs in sub-system 106 are correlated with geographical location information defining a coverage area for each channel group.
  • the NAM sub-system 106 determines which of the channel groups in the PRL for the selected NAM corresponds to the coordinate system point in the location signal and selects that channel group.
  • the NAM sub-system 106 supplies the channels listed in the selected channel group in a channel signal on an output on line 116.
  • the wireless device 102 avoids the time-consuming process of scanning channels starting at the beginning of the channel group listings in the PRL regardless of the location of the wireless device within the coverage area for the NAM. That is, the scanning begins with those channels known to be associated with the carrier cell within which the wireless device 102 is located.
  • carriers have a preferred order for acquiring channels in a channel group coverage area, and the channels in the selected channel group are presented in the carrier preferred order in the channels signal.
  • a wireless device typically goes into deep sleep when moving out of the selected NAM coverage area. However, if the wireless device 102 moves out of the selected NAM coverage area, the NAM sub-system 106 selects a new NAM and a new PRL channel group, as described above, using location information in the updated location signal.
  • E911 Phase II includes position location requirements. That is, a wireless device placing a 911 emergency call is supposed to supply location information within a predetermined period of time. One way to supply this location information is to acquire a Code Division Multiple Access (CDMA) channel. However, a typical pattern for acquiring a channel for a 911 call is biased toward acquiring an Advanced Mobile Phone Service (AMPS) channel.
  • the system 100 is used to increase the probability of acquiring a CDMA channel for a 911 call.
  • the NAM sub-system has an input to accept an emergency signal on line 118, the emergency signal indicating that an emergency call has been placed from the wireless device 102. In response to accepting the emergency signal on line 118 and the location signal on line 110, the NAM sub-system 106 supplies the channel signal on line 116 as follows.
  • the wireless device 102 For a predetermined period of time, only CDMA channels from the selected channel group are included in the channel signal, allowing the wireless device 102 the opportunity to acquire a CDMA channel and supply E911 Phase II position location information. However, the location information requirements must be balanced with the need to contact emergency personnel as soon as possible, hence the restriction of a predetermined period of time in which to acquire a CDMA channel. Determining the length of the predetermined time period falls outside the scope of system 100. If the wireless device 102 does not acquire a CDMA channel by the end of the predetermined time period, the NAM sub-system 106 supplies all channels from the selected PRL channel group. That is, the wireless device 102 then acquires the first available channel, regardless of the ability of the channel to provide location information. In some embodiments, the locator sub-system 104 includes a Global

  • the locator sub-system 104 supplies the GPS position information in the location signal. Alternately, the locator sub-system 104 accepts location position information from an external source (not shown).
  • a user interface can be used to manually select a NAM from wireless device memory. Therefore, the system 100 also includes a user interface 122 with an output to supply a user select signal on line 124 identifying a NAM stored in the NAM sub-system 106.
  • the NAM sub-system 106 includes an input to accept the user sfclect signal on line 124 and selects the NAM identified in the user select signal.
